Safety Information
Safety Information
NOTE: THIS SAFETY INFORMATION IS OF A GENERAL NATURE AND MAY BE SUPERSEDED BY INSTRUCTIONS CONTAINED WITHIN THIS
MANUAL.
1. Save the carton and packing material even if the equipment has arrived in good condition. If you ever need to ship the unit, use only the
original factory packing.
2. Read all documentation before operating your equipment. Retain all documentation for future reference.
3. Follow all instructions printed on unit chassis for proper operation.
4. Do not spill water or other liquids into or on the unit, or operate the unit while standing in liquid.
5. Make sure power outlets conform to the power requirements listed on the back of the unit.
6. Do not use the unit if the electrical power cord is frayed or broken. The power supply cords should be routed so that they are not likely to be
walked on or pinched by items placed upon or against them, paying particular attention to cords and plugs, convenience receptacles, and
the point where they exit.
7. Always operate the unit with the AC ground wire connected to the electrical system ground. Precautions should be taken so that the means
of grounding of a piece of equipment is not defeated.
8. Voltage must be correct and the same as that printed on the rear of the unit. Damage caused by connection to improper AC voltage is not
covered by any warranty.
9. Power down and disconnect the unit from mains voltage before making connections.
10. Never hold a power switch in the “ON” position.
11. Do not use the unit near stoves, heat registers, radiators, or other heat-producing devices.
12. Do not block fan intake or exhaust ports. Do not operate equipment on a surface or in an environment which may impede the normal flow
of air around the unit, such as a bed, rug, carpet, or completely enclosed rack. If the unit is used in an extremely dusty or smoky
environment, the unit should be periodically “blown free” of foreign matter.
13. Do not remove the cover. Removing the cover will expose you to potentially dangerous voltages. There are no user-serviceable parts inside.
14. Do not drive the inputs with a signal level greater than that required to drive equipment to full output.
15. The power cord of equipment should be unplugged from the outlet when left unused for a long period of time.
16. Service information equipment should be serviced by qualified service personnel when:
A. The power supply cord or the plug has been damaged.
B. Objects have fallen, or liquid has been spilled into the equipment.
C. The equipment has been exposed to rain.
D. The equipment does not appear to operate normally or exhibits a marked change in performance.
E. The equipment has been dropped, or the enclosure damaged.

3.4 Installing the Switch
1. Study the panel drawings and become familiar with the signal input-output, power requirements, plus any controls present.
2. Before using the switch, make sure that the device you want to connect to its inputs is functioning properly. Verify that the
video and audio signals are present and are being displayed on a suitable device.
3. Connect the appropriate cables between the output of the device you want to distrbute to the devices you want to input a
signal to.
4. Connect the 12-VDC, 2-A power supply to the switch and then plug the attached cord into a functioning AC outlet.

Chapter 4: Operation
4. Operation
4.1 Operating the Unit
After you connect the switch as described in Chapter 3, make sure that the inputs are being fed appropriate signals and are not
losing signals because of cable problems or problems with the source device. If the input signals to the switch are appropriate,
switch the power ON. You should see and hear the signals on the devices you have connected to the various output connectors of
the switch.
4.2 Power and Connections
The switch is not disconnected from the AC power source as long as it is connected to the wall outlet. The OFF state for the unit is
called Standby mode. In standby mode, the unit consumes a reduced quantity of power compared to normal operating modes.
When not using the switch for a long period of time, make sure that the AC power cord is disconnected from the wall outlet.
The AC wall outlet should be installed near the unit and be easily accessible.
CAUTION: Do not plug in or attempt to operate a damaged unit.

5. RS-232 Serial Interface and Commands
For a complete list of commands, refer to the extended RS-232 Protocol Instruction Manual.

You can control the switch via the RS-232 serial control port to interface to a PC or similar third-party control system.
The serial communication parameters are 9600 baud, 8 bit, no parity, and 1 stop bit. This is often referred to as 9600 8N1. When the unit
recognizes a complete command, it will perform the requested action. There is no delimiter character required.

Chapter 6: Troubleshooting
6. Troubleshooting
6.1 Common Problems
Problem: You get a “no signal” with the switch outputs.
Solutions:
1. Make certain that the signal being fed to its inputs is acceptable. Disconnect the cables from the switch inputs and connect
them directly to an appropriate monitoring device. If you do not see or hear a signal, the problem may be the signal source
itself. Also check that the AC outlet you have used to power the switch is actually providing power. Check the wall switch,
which often controls an AC outlet.
2. The second most common problem with this switch revolves around the cables. Inspect the cables for loose connectors or
cable damage such as crushed cable or cables with cuts or nicks. Replace any cable with these problems. You must use the
highest-quality cables if you want to achieve the best results. Poor-quality cables will provide poor-quality signals.
6.2 Contacting Black Box
If you determine that your 8X8 VGA Matrix Switch is malfunctioning, do not attempt to alter or repair the unit. It contains no user-serviceable
parts. Contact Black Box Technical Support at 724-746-5500 or info@blackbox.com.
Before you do, make a record of the history of the problem. We will be able to provide more efficient and accurate assistance if you have a
complete description, including:
• the nature and duration of the problem.
• when the problem occurs.
• the components involved in the problem.
• any particular application that, when used, appears to create the problem or make it worse.
6.3 Shipping and Packaging
If you need to transport or ship your 8X8 VGA Matrix Switch:
• Package it carefully. We recommend that you use the original container.
• If you are returning the unit, make sure you include everything you received with it. Before you ship for return or repair, contact Black Box to
get a Return Authorization (RA) number.
